Choose the correct phrase to complete the sentence.

My friend is flying to another country next week. She ___ get a passport before the trip, or they won't let her on the plane! ✈️

The correct answer is needs to.

"Needs to" expresses necessity — something that is required. A passport is essential for international travel, so without one she cannot fly. "Doesn't have to" would mean a passport is optional, which is incorrect here.
